Über mich

As a Senior Full-stack JavaScript/TypeScript Developer with over 10 years of experience, I am eager to leverage my expertise to drive success for your projects. My passion for web development, paired with deep knowledge of modern Frontend applications, APIs, and backend services, makes me a strong fit for any role requiring innovation and technical excellence.

My Tech Stack Includes:
Frameworks & Languages: Next.js, React.js, TypeScript, JavaScript, Express.js, Astro, Webpack
State Management: Zustand, React Query, Redux, Jotai
UI & Styling: Tailwind CSS, Headless components (Radix UI, Shadcn/ui), React Table, Material UI, Semantic UI, styled-components
AI: Open AI APIs
Realtime Messaging: RabbitMQ, PubNub, socket.io
Testing: Jest
Databases: MySQL, MongoDB
DevOps & Tools: Git (GitHub, Bitbucket), Docker, Docker Compose, Continuous Deployment (GitHub Actions), Notion, JIRA, Confluence
Cloud & Integrations: AWS, Stripe, Paddle, Google Maps (Location APIs)

I have hands-on experience building projects from scratch — covering ideation, development, and monetization. A notable example is conversiontools.io, which now serves 60k monthly active users. My expertise spans creating feasible architectures, integrating payment gateways like Stripe and Paddle, leveraging AWS for deployment, and enhancing UX with tools like Google Maps for location-based features.

In the UI domain, I specialize in crafting reusable, accessible interfaces using headless components (e.g., Radix UI, Shadcn/ui) and frameworks like Tailwind CSS, alongside advanced data handling with React Query and React Table for dynamic, performant tables.

With over 8 years of remote work experience, I thrive both independently and in collaborative team settings. My personal skills include being a fast learner, detail-oriented, self-motivated, and adept at analytical problem-solving.

I am available to start immediately and would welcome the opportunity to discuss how I can contribute to your projects. Let’s connect to explore the details further!
